Pneumonia and the role of dentistry on ICU Staff: 8-year analysis of health indicators

Abstract

Ventilator-associated pneumonia (VAP) is one of the most prevalent healthcare-associated infections (HAI) and causes of death in intensive care units (ICUs), and studies have shown its relation to oral health. Aim: To report the impact of the incorporation of dental professionals into multidisciplinary ICU staff on the incidence of VAP. Methods: A retrospective observational study was carried out to collect and analyze health indicators of patients in the ICUs from 2011 to 2018 and to differentiate these indicators between the periods before and after the participation of dental staff in the ICU. This study was approved by the Research Ethics Committee. Results: The average number of monthly ICU admissions was 105.89 ± 169.72, and the discharge was 105.21 ± 168.96, with a monthly average number of deaths within 24 h of 38.61 ± 62.27. The average number of monthly HAI-related deaths decreased from 2011 to 2018, followed by a reduction in cases of HAI per month. The average monthly number of HAIs related to mechanical ventilation (MV) decreased, and the same was observed for the infection density of HAIs related to MV (p < 0.001). In multivariate analysis, there was a significant decrease in the number of HAIs related to MV (p = 0.005). Conclusion: Although a reduction in the number of admissions or complexity of cases was not observed in the study period, multidisciplinary staff practices were essential for controlling HAIs and the presence of dental professionals can assist in the control of HAIs related to MV.
